Differences Between Horizontal and Vertical Screw-Air Water Meters
I. Appearance and Size
Horizontal Screw-Air Water Meter: Relatively small in size, but usually requires an extension pipe section for installation.

Vertical Screw-Air Water Meter: Larger in size, with an internal filter screen, and relatively less demanding on water quality.
II. Structural Design
Horizontal Screw-Air Water Meter: The impeller shaft is placed horizontally, and the water flows horizontally, with the flow direction parallel to the impeller shaft.

Vertical Screw-Air Water Meter: The impeller shaft is placed vertically, with the water flowing from a lower inlet to a higher outlet, and the flow direction perpendicular to the impeller shaft.

III. Performance Characteristics and Applicable Scenarios
Horizontal Screw-Air Water Meter: Good throughput and low pressure loss, suitable for high or ultra-high flow scenarios, such as chemical plants and power plants. Long-term high-pressure operation causes less damage to the mechanism, and it can accurately measure even under short-term overload. Vertical rotor water meters: Offer good starting flow performance and high metering accuracy, suitable for small to medium flow scenarios, such as main meters for residential buildings and businesses. They have a built-in filter, making them suitable for environments with poor water quality.
In summary, horizontal rotor water meters are geared towards high flow rates and low pressure loss applications, while vertical rotor water meters are more suitable for small to medium flow rates and high-precision metering. The actual selection should be based on a comprehensive consideration of specific water usage needs and water quality conditions.
